Crockpot Mongolian Beef Recipe

This post may contain affiliate links, please see the Disclosure for details.

Let me tell you, this slow cooker Mongolian beef is a total weeknight hero at our house. It’s rich, saucy, a little sweet, and completely satisfying. You just toss everything in the crockpot, let it cook, and boom, dinner tastes like it came from your favorite Chinese takeout spot. I make this when I want something cozy, delicious, and kid-approved without standing at the stove all evening.

Serves: 5 hungry people
Total Time: About 10 minutes of prep, then 3 hours on HIGH or 4 to 5 hours on LOW in the slow cooker

What You’ll Need

• 1 1/2 pounds flank steak, sliced thin against the grain (makes it super tender)
• 1/4 cup cornstarch
• 1 tablespoon toasted sesame oil
• 1 teaspoon minced garlic (I just use the kind in the jar, so easy)
• 1 teaspoon minced fresh ginger (again, the jar kind is totally fine)
• 1/2 cup low sodium soy sauce
• 1/3 cup brown sugar
• 1/2 cup water
• 1/2 cup green onions, chopped into 1/2-inch pieces

Mom Tips Before You Start

• Freeze the steak for 15 to 20 minutes before slicing. It makes cutting so much easier.
• If you can’t find flank steak, skirt steak or thinly sliced sirloin works great too.
• This dish is amazing with steamed rice and a green veggie like broccoli or snap peas.

How to Make It

1. Coat the steak
   Toss your sliced flank steak in a bowl with the cornstarch. Get every piece nicely coated. This helps thicken the sauce while it cooks.
2. Layer it up
   Add the beef to your slow cooker. Then pour in the sesame oil, garlic, ginger, soy sauce, brown sugar, and water. Give it all a gentle stir to combine.
3. Let it cook
   Cover and cook on HIGH for 2 to 3 hours or LOW for 4 to 5 hours. The beef should be tender and the sauce slightly thickened.
4. Finish it up
   Stir in the green onions right before serving. They add a pop of color and fresh flavor.
5. Time to eat
   Serve it hot over fluffy rice. Sprinkle on a few sesame seeds if you want to get a little fancy. My family devours this every single time.

Got Leftovers?

Store any leftovers in the fridge for up to 3 days. It reheats like a dream. Just warm it gently in the microwave or on the stove.
